[Mithalwen]

The only person who might, and I stress might, in my opinion - and more it is a feeling than anything I could prove, is Elrond. Of all the powerful people in the books he is the least ambitious. He is wise and knows the score. I think maybe if he had taken the ring from Sauron's hand, maybe he could have done it. The fire was close, Sauron was presumably at his weakest. He may have been slower to influence than Isildur. But I don't think he could have made Frodo's journey and done it.
